This is advantageous because it is often necessary or desirable to test the burners or lights.

The fact that the spindle of the push button extends through the casing or housing 20 does not prevent the latter from being made sufficiently tight against the ingress of dust and other undesirable things, such as would interfere with the mechanism.

. What I claim is:

' 1 Mechanism for automatically operating the combination of a rotary gas valve, a valve operatingratchct wheel, a clock driven member provided with a pawl adapted to normally drive the ratchet wheel and having a range of motion in .respect to said member sutlicient for permitting advancing motion of the ratchet provided with a pawl adapted to drive the ratchet wheel, whereby said clock driven member remains at rest and the first mentioned pawl is moved in respect to it when the last mentioned l pawl, substantially as described. l 2. Mechanism for automatically operating l was which comprises the combination of.

. wheel, and a a plug valve provided with a ratchet wheel, 7

a disk provided with an adjustable arm, clock-work for driving the :dislr, a pawl adapted to drive the ratchet wheel and pivoted to the arm and having its tail adapted to abut on the disk, a movable arm, manual means for turning the last mentioned arm, and a pawl carried by the last mentioned arm and adapted to cooperate with the ratchet wheel, substantially as described.

3. In mechanism for automatically opcr-' ating valves the combination of a plug valve provided with a'ratchet wheel and tixed stop, a bell crank lever the arms of which are arranged to abut upon said stop, a pawl pivoted to one of said arms and having'its tail arranged to collide with said stop to position the pawl clear of the ratchet wheel, means for normally positioning the bell. crank lever to lift the pawl clear of the ratchet wheel, a valve operating ratchel clock driven member rovided with a pawl adapted to normally drive the ratchet wheel and having a range of motion in respect to said member sufficient for permitting advancing motion of the ratchet wheel, substantially as described.

In testimony whereof I have hereunto signed my name.
